It is sometimes necessary that the 'i'usee 23 be used to hold the plate 6 in its set position to hold the arm 8 in its operative position, and it will be apparent that as soon as the tueee burns down to a pointin line with the outer end 01": the plate 6 that said plate will be released, and the spring Ll will force the same outwardly, thus freeing the extension 10 and permitting the arm 8 to swing downwardly and out of the way so that should another train equipped with a tripping arm travel over the track it will not be stopped. The arm 8 is inclined slightly outwardly so that when the tusee burns down and releases the plate (3 the weight of the arm will cause the same to swing out oi the way.

l/Vhat is claimed is:

1. A device or the class described comprising a clamp for detachable engagement with a rail, a platform supported by the clamp, an arm pivotally supported by the platform, a plate adapted to hold the arm in its operative position, and detachable means for positively holding the plate in a position to hold the arm in its operative po sition.

2. A device of the class described comprising a resilient clamp adapted for de tachalole engagement with a rail, a platform supported by the clamp, an arm pivotally supported on the platform and having a flange carried thereby, a plate slidahly mounted on the platform and adapted to cooperate with the flange to hold the arm in f ts operative position.

3. A device of the class described comprising a clamp for detachable engagement with a rail, a platform supported by the clamp, an arm pivotally supported by the platiorm, a spring pressed plate cooperatively associated with the arm to hold the in a vertical or operative position, and means for supporting a tnsee in aposition to hold the plate in such position as to hold the arm in its operative position, said plate being released when the tusee burns to a predetermined point.

at. A device of the class described comprising a clamp adapted to detachably engage a rail, a platform carried by the clamp, a support carried by the platform for supporting a fusee, a plate slidabl mounted on the platform and having one end adapted to engage the fusee, an arm pivotally supported by the platform and having an extension cooperative therewith tor engagement with the plate to hold the arm in its operative position, and yieldable means for sliding the plate in one direction, when the tus-ee burns to a predetermined point, for releasing said arm, as and for the purpose set forth.

In testimony whereof I atlix my signature.
